18 GroupWise 7 Multi-System Administration GuideFor information about installing the Internet Agent, see “Installing the GroupWise Internet Agent”in the GroupWise 7 Installation Guide.2.3 Setting Up Internet-Style AddressingDynamic Internet links require your GroupWise system to be configured to use Internet-styleaddressing (user@hostname) rather than standard GroupWise addressing(userID.post_office.domain). If you have not enabled Internet-style addressing and defined at leastone Internet domain for your GroupWise system, see “Configuring Internet Addressing” in theGroupWise 7 Administration Guide.The Internet domains you establish when setting up Internet-style addressing (for example,novell.com, groupwise.novell.com, and support.novell.com) are the key to enabling dynamicInternet links. Each MTA that will receive messages must be defined in DNS and associated withthe Internet domain (or domains) that it will receive messages for. This allows MTAs in otherGroupWise systems to route messages that contain your Internet domain names to the appropriateMTAs in your system.2.4 Adding MTA Resource Records to DNSIn order for your GroupWise system to receive messages from another GroupWise system via adynamic Internet link, you need to create a DNS resource record for at least one of your MTAs. Theresource record enables the MTA’s address, along with the Internet domain names associated withit, to be broadcast throughout the Internet.You need to create the following resource records in DNS: An address ("A") record that maps the MTA server’s host name to its IP address. A service ("SRV") record or a text ("TXT") record that maps the Internet domain name to thehost name or IP address assigned to the MTA’s server.You can use your tool of choice to modify DNS. The following sections explain the informationrequired and provide sample records. Section 2.4.1, “Creating the Address ("A") Record,” on page 18 Section 2.4.2, “Creating the Service ("SRV") or Text ("TXT") Record,” on page 192.4.1 Creating the Address ("A") RecordYou can create an "A" record to map your MTA server’s fully-qualified host name to its IP address.Doing so enables you to use the server’s fully-qualified host name in the service ("SRV") or text("TXT") record rather than the IP address. The "A" record is required if you plan to use a "SRV"record.The following text shows sample "A" records.;; Address ("A") records;localhost IN A 172.0.0.1corp.serv.novl IN A 172.16.5.18gwdev.serv.novl IN A 172.16.5.19gwsup.serv.novl IN A 172.16.5.20
